Williamson County has no dark-sky lighting ordinance for private property. Texas has no general outdoor-lighting statute; Health and Safety Code Chapter 425 covers only state-funded fixtures and areas near observatories or military bases, none of which sit in the county.
No Williamson County ordinance requires shielded or dark-sky-compliant lighting on private homes and businesses. Texas has no statewide dark-sky law for private property. Health and Safety Code Chapter 425 sets cutoff-luminaire standards only for outdoor lighting installed with state funds, and separate provisions let counties regulate lighting near a large observatory or military installation - neither of which is in Williamson County. Dark-sky rules that homeowners in Georgetown, Leander, or Sun City subdivisions must follow come from HOA deed restrictions, not the county. Cities may adopt their own lighting standards inside their limits.
The county issues no dark-sky citations to private property owners because no ordinance applies. HOAs enforce lighting covenants through civil action, and state-fund lighting standards bind government projects, not residents.
